DISPLAY-STAND FOR ELECTRIC-LIGHT LAM PS.

Application filed June 15, 1918. Serial No. 108,797

To all whom it may 'c'onoem:

Be it known that I, CLARENCE W. Win, a citizen of the United States, residing at Johnstown, in the county of Cambria and State of-Pennsylvania, have invented certain new and useful Improvements in Display- Stands for Electric-Light Lamps,'of which the following is a specification, reference being had to the accompanying drawlngs.

for its primary object to provide a very simply constructed and serviceable device for displaying to prospective purchasers a multiplicity of lamps.

The invention has for one of its more particular objects to provide a rotary display table in which the several lamps are suitably i mounted, a circuit for the lamps, a central relatively stationary socket'to receive a test lamp, and improvedmeans for successively closing the circuit for the display lamps as said table is rotated.

It is a further general object of my inven tion to provide a display device ofthe above character, the several parts of which are ex ceedingly simple in construction and can be cheaply Iiianufactured and assembled, said device being highly serviceable and advantageous for the attractive display of a large number of lamps of different styles.

With the above and other objects in. View, my inventionconsists in the-novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view illustrating the preferred embodiment of my improved display device;

Fig. 2 is a plan view of the base; and

Fig. 3 is an inverted plan view of the rota lamp carrying table.

eferrmg in detail to the drawing, 5 indicates the base of the device which may be of Wood or-other suitable material of any desired ornamental form. In a bracket 6, centrally fixed upon the upper surface of the base 5, a tubular rod or standard 7 is suitably mounted.'- 9 and 10 designate metallic circuit closing strips which are fixed at their outer ends upon the base 5 and are u wardly curved, as clearl shown .in,Fig. 1, tlie inner free ends of sai strips being angularly oil'- set upwardly, asat 11,,and preferably hav' I ing their terminals downwardly bent or curved. The innerfree end of the circuit closing strip 10 is disposed at one side of the standard] and preferably closer thereto than the upwardly extending end of .the

purpose and manner of operation of these Patented Mar. 20, 1917. I

. other circuit zlosing strip 9. The particular metallic strips 10 and 9 Wlll hereinafter set forth.

12 designates the rotary table, preferably, This invention relates to improved (llS i play stands for electric light lamps and has through not necessarily, of circularlfonn in plan, WlllCl). 1s mounted to turn freely upon the base 5, the top wall ofsaid table being centrally pro rided with an opening through which the up per end of the standard 7 'extends. A c1 .cular series of equi-distantly spaced lamp receiving sockets 13 are suita- My secured in the top wall of the table 12,

erably, the lamp plug and socket are unthreaded so that the plug may be easily and quickly fitted into the socket or' removed therefrom.

, A plurality of dependin rods 15 are fixed to the top wall of the ta le 12 and to the lower ends 0:, these rods a rigid sheet of in-.

sulating mat srial 16 is connected. This insulating sheet is provided with a central opening, ind cated at 17 to receive the cen-- tral standarc' 7 and upon the under side of said insulating sheet, a metal annulus 18 is fixed in cones ntric relation to the opening 17.

In spaced 1% :lation to this annulus, a. plusaid plates being equal in number to" the number of limpreceiving sockets 13 inthe rotary table.

rality of spa zedimetal plates'19 are secured,

an opening '21 in thebase 5. The wire QO i s connected tc the fixed end of the circuit closing strip 9 and the wire 20 is connected to the fixed e ad of the metal strip 10'. Wires 22 and 22 are also connected to the fixed ends of the respective circuit closing strips.

and extend a wardly through the tubular standard 7 an are connected tothe contacts of the-lam socket 14. A wire indicated at 23 is meta licallymonnected to the annulus 18 and to a metallic conductor 'of oneofy-the lot lamp sockets 13 connected to one side of the circuit. These conductors of the sev al lamp sockets are metallically connected by a wire 24, and the opposite side of the circuit through each ofthe plugs 13, is connected b means of a wire 25, to one of the metal p ates 19.

When the several parts of the device are assembled, the free end of the circuit closing strip 9 has resilient bearing contact with the metal annulus 18, while the strip 10 iseng aged upon one of the metal plates 19. The ends of the circuit wires 20 and 20 are con nected to a suitable switch, and when the test lamp L is engaged in the socket H, the circuit will be closed through the wires 20 and 20 and the wires 22 and E22 and said lamp illuminated. The strip 9 bearing upon the annulus 18, also closes one side of the circuit through said strip, thc wire 22, plate 18, wire 23 and the circular wire 24 to the corresponding conductors of the lamp circuits 13. When the table 12 is rotated, the tree end of the resilient strip 10 successively passes from one of the plates 1U to another. The strip 10, as it bears upon one of said plates, closes the circuit through the wire 25 to one of the sockets so that the lamp engaged in this particular socket will be illuminated. When the end of the strip 10 moves off of this plate 19, the circuit is immediately broken to said lamp and the circuit of the next adjacent lamp is closed, when the free end of the strip 10 contacts with'the next plate 19. Thus in the rotation of thetable 12, it will be seen that the several lamps carried thereby, are successii'ely illuminated, thereby accentuatin; the particular attractive features of the vidual lamps in adistinctive manner. It is understood, of course, that the central test lamp 11' remains illuminated at all times during the rotation of the table.

From the foregoing description taken in connection with the accompanying drawings, it is thought that the construction, manner of operation. vand severa-ladvantages of my invention will-be clearly and fully understood. lhe formation and arrangement of theseveral parts of the-device being quite simple, enables the device to be constructed at relativelyysniall manufacturing cost. It

manifest that the table 12,;may be of any desired size, and that the number-"of lamp sockets ca'rried thereby can be increased or decreased innumber as desired. It is also within the purview my invention to adopt various other means-for mounting the rotary table than that disclosed in the accompanyir'rg drawing. which is for illust ative purposes only. Inpractical'use I- have found my improved lamp display device to be i'ghly desirable and serviceable'in interestmg prospectivepurchasers and promoting the sale of the lanips.

indi I changes as may be l'airly cmbodicd wit-hill.

the spirit and scope of the invcntirm, as claimed.

Having thus described this invei'ition, what I desire to claim as new and secure by Letters Patent, is:--

1. An electric lamp display device including a base, a table rotatably mounted thereon, a plurality of spaced sockets carried by the table, to receive the lamps to be displayed, a central relatively stationary socket mounted above the table to receive a test lamp, and a circuit'tor said lamps including circuit closing strips fixed upon the base, and means carried by the table to be engaged by the respcetim circuit closing strips to close the circuit and successively illuminate the display lamps in the. rotation of the table, said nuraus in luding a conductor in, constant engagement with one of said strips to maintain the circuit chased tl'irough the test lamp.

2. An electric. lamp display device including a base, a table rotatably mounted thereon, a. plurality of spaced sockets carried by the table to receive the lamps to be displayed, a centrally lixcd standard projecting above the table, a socket upon the upper end of: said standard to receive a test burn and a. circuit for said lamps including spaced rcsilient circuit losing strips connectel'l to opposite sides of the circuit, a metal annulus carried by the table and engaged by one of said strips, and means at all times connect ing said annulus to one side of the circuit through the lamp sockets on the table, and spaeer'l metal plates carried by the table and individually connected. to the respective lamp sockets and adapted to be successively engaged by the other of the circuit closing strips in the rotation of the table, whereby the'circuit is successively closed tin-(nigh the display lamps when the table is rotated.
